Found this bug after my son screamed about being bit. It does not seem to fly. In the center of its back is a bronze oval that looks a little like a small leaf. If has a long red tube for its mouth with long antennea. (New Iberia, LA)
it is an adult wheel bug. It is named after the spiky looking ‘wheel’ on its backside behind the head.
They do bite with its long piercing sucking ‘red’ mouth parts and it is said to be very painful.
CAUTION: The adult wheelbug is reported to inflict a very painful bite. It has been reported use of ammonia water or Epsom salts is helpful in relieving pain from the bite.
The nymphs and adults are great predators to have in the garden to get rid of caterpillars, aphids, etc
They overwinter in the egg stage then emerge in spring to grow into the adults. There is just one generation per year.
